Product Overview
The AT4050ST from Audio-Technica brings you the realism of a live sound field. It's a stereo, side-address condenser microphone that features independent cardioid and figure-of-eight elements, all configured in a Mid-Side arrangement. It's an innovative mic that allows sound recordists the choice of selecting either a left-right stereo output or discrete Mid-Side signals for later manipulation — notable versatility. The mic’s dual-diaphragm capsules maintain a precise polar pattern definition across the full frequency range. Plus, its transformerless circuitry virtually eliminates low-frequency distortion.
